Vice Adm. John D. Alexander is one of the most accomplished military leaders to come from Southeast Texas. A native of Port Neches, Texas, Alexander spent 37 years in the United States Navy, rising from a newly commissioned naval flight officer to become the 29th commander of the U.S. Third Fleet, one of the Navy’s principal operational commands responsible for the eastern Pacific Ocean.

​

Alexander graduated from Texas Tech University in 1982 with a Bachelor of Science in Mechanical Engineering and entered the Navy through the Aviation Officer Candidate Program. He was commissioned in December 1982 and designated a Naval Flight Officer in November 1983. Early in his career, he served as an A-6E Intruder bombardier/navigator with Attack Squadrons VA-165, VA-155, and VA-196. These assignments placed him aboard major aircraft carriers including USS Kitty Hawk, USS Independence, and USS Carl Vinson, where he participated in carrier-based strike operations and developed the aviation experience that would define much of his career.

​

As his responsibilities increased, Alexander became an instructor with VA-128, training future naval flight officers on the A-6E Intruder. He later served as strike operations officer with Cruiser Destroyer Group 3 and held several key personnel and staff assignments, including Aviation Commander Detailer at Navy Personnel Command and Executive Assistant to the Director of the Joint Staff in Washington, D.C. These assignments exposed him to both operational planning and the management of Navy personnel at the highest levels.

​

Alexander’s command career began with Electronic Attack Squadron VAQ-135, the “Black Ravens,” where he led electronic warfare missions aboard USS Carl Vinson and supported operations from Incirlik, Turkey. He later commanded USS Juneau (LPD-10), an amphibious transport dock forward-deployed to Sasebo, Japan. During his command, the ship participated in multinational exercises throughout the Pacific, including Cobra Gold in Thailand, Balikatan in the Philippines, Foal Eagle in South Korea, and Talisman Sabre with Australian forces.

​

From 2010 to 2012, Alexander commanded the nuclear-powered aircraft carrier USS Abraham Lincoln (CVN-72). During two major deployments, the ship supported Operation Enduring Freedom in Afghanistan, launching thousands of combat sorties and delivering hundreds of thousands of pounds of ordnance. Under his leadership, Abraham Lincoln conducted operations across the Pacific, Indian Ocean, Arabian Sea, and Mediterranean Sea before relocating its homeport from Washington state to Norfolk, Virginia.

​

Promoted to flag rank, Alexander served as Assistant Commander for Career Management at Navy Personnel Command, Director of Maritime Operations for U.S. Fleet Forces Command, and Commander of Carrier Strike Group Five and Battle Force U.S. Seventh Fleet aboard USS Ronald Reagan in Yokosuka, Japan. In these roles he directed carrier strike group operations throughout the Indo-Pacific region and worked closely with allied navies on multinational exercises and regional security operations.

In September 2017, Alexander assumed command of the U.S. Third Fleet. As commander, he oversaw fleet readiness, training, and operations across the eastern Pacific and played a leading role in the 2018 Rim of the Pacific (RIMPAC) exercise, the world’s largest international maritime exercise involving more than two dozen nations. He remained in command until his retirement in September 2019.

​

Throughout his naval career, Alexander accumulated more than 3,200 flight hours and over 700 carrier-arrested landings. His decorations include the Defense Distinguished Service Medal, Defense Superior Service Medal, multiple awards of the Legion of Merit, Air Medals, Meritorious Service Medals, and numerous campaign and service awards. In recognition of his professional accomplishments, Texas Tech University named him both a Distinguished Engineer and a Distinguished Alumnus. Following retirement, he continued supporting naval aviation history and education as a trustee of the Naval Aviation Museum Foundation.
